Hume's leaf warbler or Hume's warbler (Phylloscopus humei) is named after Allan Octavian Hume, a British civil servant and ornithologist based in India, who founded the Indian National Congress party. He has been called the Father of Indian Ornithology. Hume's leaf warbler is one of the smallest "Old World warblers". Like most other leaf warblers, it has greenish upperparts and off-white underparts. It is very similar to the yellow-browed warbler (P. inornatus). However, it has only one prominent light wing bar, just a faint vestige of the second shorter wing bar, and overall duller colours. It also has a dark lower mandible and legs.
